Azure Quickstart

Set up the application

Visit https://apps.dev.microsoft.com/ to register an application on Azure AD. The application’s “Redirect URI” must be http://localhost:5000/login/azure/authorized. You can also follow the detailed steps described at: https://azure.microsoft.com/en-us/documentation/articles/active-directory-v2-app-registration/ Take note of the “Application ID” (Client ID) and “Password” (Client Secret) for the application.

Code

from flask import Flask, redirect, url_for
from flask_dance.contrib.azure import make_azure_blueprint, azure

app = Flask(__name__)
app.secret_key = "supersekrit"
blueprint = make_azure_blueprint(
    client_id="my-key-here",
    client_secret="my-secret-here",
)
app.register_blueprint(blueprint, url_prefix="/login")

@app.route("/")
def index():
    if not azure.authorized:
        return redirect(url_for("azure.login"))
    resp = azure.get("/v1.0/me")
    assert resp.ok
    return "You are {mail} on Azure AD".format(mail=resp.json()["mail"])

if __name__ == "__main__":
    app.run()

Note

You must replace my-key-here and my-secret-here with the client ID and client secret that you got from your Azure application.

Note

If you are running this code on Heroku, you’ll need to use the werkzeug.contrib.fixers.ProxyFix middleware. See Proxies and HTTPS.

If you run this code locally or without HTTPS enabled (see warning below), you must set the OAUTHLIB_INSECURE_TRANSPORT environment variable to disable the HTTPS requirement imposed by oauthlib, which is part of Flask-Dance. For example, if you put this code in a file named azure.py on your machine, you could run:

$ export OAUTHLIB_INSECURE_TRANSPORT=1
$ python azure.py

Visit `http://localhost:5000`_ in your browser, and you should start the OAuth dance immediately.

Warning

OAUTHLIB_INSECURE_TRANSPORT should only be used for local testing or over trusted connections. By default, all OAuth interactions must occur over secure https connections (this is enfored by oauthlib). However, setting OAUTHLIB_INSECURE_TRANSPORT disables this enforcement and allows OAuth to occur over insecure http connections.

Explanation

This code makes a blueprint that implements the views necessary to be a consumer in the OAuth dance. The blueprint has two views: /azure, which is the view that the user visits to begin the OAuth dance, and /azure/authorized, which is the view that the user is redirected to at the end of the OAuth dance. Because we set the url_prefix to be /login, the end result is that the views are at /login/azure and /login/azure/authorized. The second view is the “authorized callback URL” that you must tell Azure about when you create the application.

The azure variable is a requests.Session instance, which will be be preloaded with the user’s access token once the user has gone through the OAuth dance. You can check the azure.authorized boolean to determine if the access token is loaded. Whether the access token is loaded or not, you can use all the normal requests methods, like get() and post(), to make HTTP requests. If you only specify the path component of the URL, the domain will default to https://graph.microsoft.com.
